aiohttp.ClientSession defaults to trust_env=False, ignoring HTTP_PROXY/
HTTPS_PROXY env vars. This causes QR login and all API calls to fail for
users behind a proxy (e.g. Clash in fake-ip mode), which is common in
China where Weixin and WeCom are primarily used.
Added trust_env=True to all aiohttp.ClientSession instantiations that
connect to external hosts (weixin: 3 places, wecom: 1, matrix: 1).
WhatsApp sessions are excluded as they only connect to localhost.
httpx-based adapters (dingtalk, signal, wecom_callback) are unaffected
as httpx defaults to trust_env=True.

Four fixes for the Weixin/WeChat adapter, synthesized from the best
aspects of community PRs #8407, #8521, #8360, #7695, #8308, #8525,
#7531, #8144, #8251.
1. Streaming cursor (▉) stuck permanently — WeChat doesn't support
message editing, so the cursor appended during streaming can never
be removed. Add SUPPORTS_MESSAGE_EDITING = False to WeixinAdapter
and check it in gateway/run.py to use an empty cursor for non-edit
platforms. (Fixes#8307, #8326)
2. Media upload failures — two bugs in _send_file():
a) upload_full_url path used PUT (404 on WeChat CDN); now uses POST.
b) aes_key was base64(raw_bytes) but the iLink API expects
base64(hex_string); images showed as grey boxes. (Fixes#8352, #7529)
Also: unified both upload paths into _upload_ciphertext(), preferring
upload_full_url. Added send_video/send_voice methods and voice_item
media builder for audio/.silk files. Added video_md5 field.
3. Markdown links stripped — WeChat can't render [text](url), so
format_message() now converts them to 'text (url)' plaintext.
Code blocks are preserved. (Fixes#7617)
4. Blank message prevention — three guards:
a) _split_text_for_weixin_delivery('') returns [] not ['']
b) send() filters empty/whitespace chunks before _send_text_chunk
c) _send_message() raises ValueError for empty text as safety net

Add content-aware splitting to compact mode: short chat-like exchanges
(2-6 short lines without headings/lists/quotes) get separate message
bubbles for a natural chat feel, while structured content (tables,
headings with body, numbered lists) stays in a single message.
Cherry-picked from PR #7587 by bravohenry, adapted to the compact/legacy
split_per_line architecture from #7903.
When sending multi-chunk responses, individual chunks can fail due to
transient iLink API errors. Previously a single failure would abort the
entire message. Now each chunk is retried with linear backoff before
giving up, and the same client_id is reused across retries for
server-side deduplication.
Configurable via config.yaml (platforms.weixin.extra) or env vars:
- send_chunk_delay_seconds (default 0.35s) — pacing between chunks
- send_chunk_retries (default 2) — max retry attempts per chunk
- send_chunk_retry_delay_seconds (default 1.0s) — base retry delay
Replaces the hardcoded 0.3s inter-chunk delay from #7903.
Salvaged from PR #7899 by @corazzione. Fixes#7836.
The Weixin adapter was splitting responses at every top-level newline,
causing notification spam (up to 70 API calls for a single long markdown
response). This salvages the best aspects of six contributor PRs:
Compact mode (new default):
- Messages under the 4000-char limit stay as a single bubble even with
multiple lines, paragraphs, and code blocks
- Only oversized messages get split at logical markdown boundaries
- Inter-chunk delay (0.3s) between chunks prevents WeChat rate-limit drops
Legacy mode (opt-in):
- Set split_multiline_messages: true in platforms.weixin.extra config
- Or set WEIXIN_SPLIT_MULTILINE_MESSAGES=true env var
- Restores the old per-line splitting behavior
Salvaged from PRs #7797 (guantoubaozi), #7792 (luoxiao6645),
#7838 (qyx596), #7825 (weedge), #7784 (sherunlock03), #7773 (JnyRoad).
Core fix unanimous across all six; config toggle from #7838; inter-chunk
delay from #7825.
